Global menu on librewolf

source: https://bazaar.launchpad.net/~mozillateam/firefox/firefox.xenial/files/1441/debian/patches Older releases of ubuntu had a patch for firefox that allowed for globar menu support (see unity-menubar.patch) as far i have seen it does not seem to break anything on other DEs (in fact it adds features especially if you use topmenu on something like XFCE)
